Simbach – Braunau railway bridge

The Simbach – Braunau railway bridge is a 400 meter long bridge over the Inn between the towns of Simbach in Bavaria and Braunau in Upper Austria . On the bridge, in the middle of the river on the German-Austrian border, the Munich – Simbach railway merges into the Neumarkt – Kallham – Braunau railway .

location

The railway bridge is roughly in the middle between the German border station Simbach (Inn) and the Austrian station Braunau am Inn . It crosses the Inn east of the city centers of Simbach and Braunau at an angle of 60 degrees. Of the five pillars of the bridge, the three eastern ones are in the river, the two western ones in the floodplain on the Bavarian side. Of the approximately 400-meter-long bridge, 228 meters to the west are operated by Deutsche Bahn and the eastern part by Austrian Federal Railways . About 350 meters southwest of the railway bridge, the Inn crosses the road bridge between Braunau and Simbach .

history

construction of the bridge

In the course of planning a main line from Munich to the Austrian state border, the Bavarian State Parliament decided in 1863 to run the line between Simbach and Braunau over the border and the Inn. On January 11, 1869, the Bavarian government approved the construction of the railway bridge over the Inn. The bridge was built by the Simbach construction section of the Bavarian State Railways under the direction of the section engineer Heinrich Fraas together with Simbach station. It was designed as a truss bridge on five brick pillars; the six openings had a clear height of 5.75 meters and clear widths of 60 meters each. The abutment and the three western pillars were on concrete foundations founded , the two eastern piers in Druckluftsenkkästen founded. This made the Inn Bridge one of the first bridges in Bavaria to use the pneumatic foundation system . The wrought - iron trusses supplied by the Maschinenbau-Gesellschaft Nürnberg Klett & Co. were designed as parallel girders with a one - piece stud frame and counter struts and were held together by a total of 163,080 rivets . The roadway was arranged on the top chord of the truss.

Endurance test with seven locomotives on May 22, 1871

According to a contract dated March 4, 1871, the Austrian Empress Elisabeth-Bahn took over the transport service from Simbach over the Inn Bridge to Braunau. The completion of the bridge was originally planned for 1870, but was delayed until mid-May 1871. The first stress test with a locomotive took place on May 18, 1871. On May 22nd, another load test was carried out with seven locomotives of the Bavarian State Railways and the Empress Elisabeth Railway with a total weight of 5612 inch cents  . On June 1, 1871, the Kaiserin Elisabeth-Bahn commenced provisional operation and on July 1, 1871, the scheduled train service over the bridge began.

Destruction and rebuilding

Towards the end of the Second World War , on May 1, 1945, shortly before the arrival of American soldiers, a Wehrmacht unit blew up the easternmost bridge pillar and the four supporting structures over the river. Only the two western structures on the Bavarian side survived the blast. To capture Braunau, American pioneers laid a provisional footbridge over the rubble of the railway bridge from Simbach on May 2, 1945. From August 1945 to February 1946 the ruins of the bridge lying in the Inn were removed. Using a pioneer bridge of the Wehrmacht, the destroyed superstructures were rebuilt in 1946, so that from December 18, 1946, trains could again cross the bridge.

View from Austria to Germany

In 1960 the Deutsche Bundesbahn replaced the two remaining western superstructures of the bridge with new supporting structures with strut trusses . The Austrian Federal Railways renewed the four eastern superstructures from 1977 to 1978 and also installed supporting structures with strut trusses instead of the pioneer bridge.
